Abstract Since the first Spanish settlers brought horses to America centuries ago, several local varieties and breeds have been established in New World. These were generally a consequence of admixture different arriving from Europe. In some instances, selectively bred for specific traits, such as appearance, endurance, strength, gait. We looked at genetics two breeds, Puerto Rican Non-Purebred (PRNPB) (also known “Criollo”) Paso Fino (PRPF), Caribbean Island Rico. While it is reasonable...
Little is known about the natural history of Sphaerodactylus species endemic to three islands located in Mona Passage separating Greater Antillean Hispaniola and Puerto Rico. In this study, parts two mitochondrial genes, 16S rRNA 12S rRNA, were sequenced determine relationships between sphaerodactylids that live other Caribbean from same genus. While main goal was identify biogeographical origin these species, we also identified a genetically distinct type dwarf gecko warrants future...
We examined population densities and structural microhabitat use by Anolis griseus A. trinitatis at eight sites on the leeward (western) coast of St. Vincent, West Indies. Estimates density based Schnabel method varied according to habitat complexity ranged 5,208/ha for (a higher estimate one site was not considered due conditions that compromised accuracy estimates) 27,923/ha trinitatis. Our highest both species (32,867/ha) yet recorded any a two-species Lesser Antillean island. For...
Las filogenias moleculares han elucidado múltiples linajes en el árbol de la vida, incluyendo varios vertebrados neotropicales. salamanquitas del género Sphaerodactylus (Sphaerodactylidae) son abundantes y forman una parte importante herpetofauna neotropical. Este ha sido investigado recientemente utilizando métodos modernos. En este artículo se describe nueva especie Sphaerodactylus, procedente región kárstica noroeste Puerto Rico. Los individuos fueron comparados con especies afines...
Abstract Conflicts and natural disasters affect entire populations of the countries involved and, in addition to thousands lives destroyed, have a substantial negative impact on scientific advances these provide. The unprovoked invasion Ukraine by Russia, devastating earthquake Turkey Syria, ongoing conflicts Middle East are just few examples. Millions people been killed or displaced, their futures uncertain. These events resulted extensive infrastructure collapse, with loss electricity,...
St. Vincent, one of the Windward Islands Lesser Antilles, is home to four amphibian species, only which (Pristimantis shrevei) endemic.Pristimantis shrevei (Strabomantidae) restricted highlands, whereas Eleutherodactylus johnstonei (Eleutherodactylidae), an introduced has become widely distributed throughout island.We established and surveyed 26 transects at three sites recorded numbers P. E. johnstonei, encounter rates, all perch types heights.In general, was more abundant in less disturbed...
Reptarenavirus es un arenavirus que mayormente ha sido detectado en serpientes cautiverio. Se cree el mismo agente etiológico de la enfermedad conocida como Boid Inclusion Body Disease (BIBD), cual mortal para los miembros las familias Boidae y Pythonidae. En Puerto Rico, boa cola roja (Boa constrictor) fue introducida durante década 1990 a través trata mascotas. Establecer programa monitoreo este virus esencial debido individuos Boa constrictor podrían actuar vectores propagar endémicas,...
The Asian freshwater snail Melanoides tuberculata has been established in the Americas since 1960s, where it transmits cercariae of a small number digenetic trematode species from its native range. In 2021-2022, 24 M. were discovered shedding transversotrematid Puerto Rico, parasites this have not previously studied. Adult transversotrematids (in some cases, gravid) found on field-caught fish and exposed to snails, including Rico. Adults identified as Transversotrema patialense (Soparkar,...
